Renal, intestinal, cerebral and ophthalmic blood flow velocities (bfv) during patent ductus arteriosus (pda)

ABSTRACT To evaluate hemodynamic effects of PDA, left ventricular output (LVO) and BFV in the renal, mesenteric, ophthalmic and median cerebral arteries were serially measured (duplex pulsed

Doppler) in 11 preterm normoventilated infants (GA 26-31 wks) during PDA and after ligation. While LVO increased, mean (m) diastolic (d) BFV's decreased gradually, whereas m-systolio

BFV's did not change significantly. LVO and BFV's normalized after ligation. The decrease of renal and mesenteric mdBFV was earlier and larger than of cerebral mdBFV, and preceded

clinical signs of PDA Similar changes of organ blood flow have been observed in lambs (Clyman et al, J Ped 111:579, 1987). Conclusion: Evaluation of regional BFV's yields additional

information on the hemodynamic significance of a PDA in preterm infants. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * Dept of Pediatrics & Div. Neonatology Dept Gyn Ob, Univ
